Power supply system - petrol models

General information and precautionary measures

The power supply system consists of a fuel tank (fixed by assembly brackets to the bottom in a back part of the car), the electric gasoline pump placed in it, the fuel filter, and also lines of giving and fuel return. The gasoline pump submits Pogruzhna fuel to the fuel highway which is carrying out a role of the accumulative tank for four injectors established in it. Injection of fuel is carried out to inlet highways of cylinders. The fuel filter is switched on in the line of supply of the fuel, going from a gasoline pump to the fuel highway and prevents possibility of a contamination of injectors.

The principle of functioning of various systems of injection is in detail stated in the section of System of injection of fuel - the general information.

Codes of engines see in Specifications to Head engine Repair.


Many from procedures described in the present Chapter demand removal of fuel lines and undocking of the shtutserny knots involving certain losses of fuel. Remember that gasoline is flying and inflammable liquid in the highest measure and demands extra care in the address!


Fuel lines continue to remain under pressure during even long time after ignition switching off. Before undocking of shtutserny connections of a power supply system it is necessary to dump before residual pressure in a path (see Sbrasyvaniye pressure in a power supply system).
